What Account Holder Verification Solves

Organisations collecting bank account details need confidence that the account information supplied belongs to the intended customer or payee/payer. Account holder verification provides an additional validation step by checking the supplied name against the account information held by the relevant bank.

PayPoint supports this through CoP/PNV for UK accounts and VoP for supported international accounts.

How CoP/PNV Works

CoP/PVN verifies the account holder’s name by querying the customer’s bank or building society. The responding institution makes the decision and returns a match result.

Useful Verification Behaviours

• For personal accounts, the exact registered name must be provided.

• For joint accounts, either name on the account may be supplied (order does not matter).

• For business accounts, the registered company name or trading name must be provided.

• Customers may opt out of CoP/PVN with their bank — in these cases, no positive/negative match will be returned.

All matching logic is performed by the customer’s own bank, not PayPoint.

Process Flow

The typical verification flow involves:

1. Client submits account holder's name + sort code + account number

2. PayPoint routes the request to the responding bank

3. Bank validates name and returns a match result

4. Client decides whether to proceed, ask the user to correct the name, or block the transaction

API Access & Documentation

PayPoint provides separate CoP/PVN and VoP APIs for account holder verification.

• CoP/PVN uses the customer’s Name, Sort Code and Account Number for UK account checks.

• VoP uses the customer’s Name and IBAN for supported international account checks.

Both services support single and batch verification requests.

Full endpoint specifications are provided in the API Documentation

FAQS

What are the difference between single and batch requests?

Singleton Requests

• Fully synchronous

• Typical response time: ~1 second (dependent on responding bank)

• CoP/PVN scheme rules require a 3-second wait before retrying once

• PayPoint timeout ≈ 7 seconds

• Clients may set a shorter local timeout if desired

Batch Requests

• Submitted as batch jobs

• PayPoint serialises requests internally

• Results are available once all individual checks complete

• Client polls the batch results endpoint

• Ideal for onboarding or nightly cleansing

What are the Rate limits?

Sandbox

The sandbox connects to the live CoP network, but is rate‑limited:

• 10 requests per 60 seconds

• 100 requests per day

Limits apply per x‑api‑key, shared across team members. Performance may be slower than production due to reduced scaling and cold‑start effects.

Production

• 10 TPS per client for single requests

• No submission limit for batch uploads

• Batch processing runs at 20 TPS

• Maximum batch file size: 2.7 MB (≈ 10,000 accounts)

How can we do automated testing?

The sandbox returns live CoP/PVN results, which may include personal data. For automated testing, PayPoint provides a complete set of canned responses using the dummy sort code 00‑00‑00. These are listed below at: Test Bank Account & Response

These simulate all possible CoP/PVN match outcomes without touching real customer data.

How does name matching work?

Name matching is controlled entirely by the responding bank. While scheme rules define minimum expectations, banks may handle edge cases differently.

Banks cannot return “No Match” when:

• First name and surname are reversed

• Family name matches and the provided first name is a common variant (e.g., William/Bill, Elizabeth/Liz)

• First name contains a single spelling error

• Family name contains a single spelling error

Banks cannot return a “Full Match” unless:

• Family name is an exact match

• First character of the first name is correct

Banks may occasionally exceed these rules and return Full Match for slight deviations — behaviour varies by institution.

CoP/PVN

A set of dummy accounts is available under sort code 00‑00‑00, covering the full spectrum of CoP/PVN response codes. Using any valid live sort code will query real bank accounts and return genuine responses.
